    Which of the following statements about skeletal muscle contraction is false? During muscle contraction, the Z discs move closer together as the myosin heads move toward the plus ends of the actin filaments. The changes in voltage across the plasma membrane that occur when a muscle cell receives a signal from the nervous system causes Ca2+ to flow into the sarcoplasmic reticulum, triggering a muscle contraction. An action potential in the muscle cell plasma membrane leads to voltage-gated calcium channels...

    The neurotransmitter acetylcholine (ACh) causes the rapid contraction of skeletal muscle and the slower relaxation of cardiac muscle. Which one of the following is the most likely explanation for this difference? A. ACh activates a GPCR pathway in cardiac muscle and an ion channel coupled receptor in skeletal muscle. B. ACh activates an ion channel coupled receptor in cardiac muscle and a GPCR pathway in cardiac muscle. C. ACh is permeable through the plasma membrane of skeletal muscle cells but...

    pls give short answers Q16 15 Points Brody myopathy is a rare genetic disorder affecting skeletal muscle. The disease is caused by an inactivating mutation in a gene that produces a protein called ATP2A1. This protein is expressed in the sarcoplasmic reticulum(SR) and helps transport calcium into the SR. Q161 5 Points Based on the role of calcium in cross-bridge cycling, does this disease cause muscle weakening or hyper-contraction? muscle weakening muscle hyper-contraction Q16.2 5 Points Why did you choose...

    8 Number the following events of skeletal muscle contraction in the proper order, with number 1 for the first event and number 6 for the last event. A power stroke occurs as myosin moves into its relaxed position and pulls the thin filament toward the M line. Calcium ions bind to troponin, which pulls tropomyosin away from actin. ATP breaks the actin-myosin attachment, after which ATP is hydrolyzed and myosin is recocked. The myosin head binds to an actin subunit....

    Question 28 4 pts Once the action potential occurs in the sarcolemma, it spreads moving down the T-tubules. What next? What is the correct order of events which result in skeletal muscle contraction? (4 points) a. Once the muscle cell action potential is initiated then calcium ions are released from the sarcoplasmic reticulum. These calcium ions bind to troponin. With this binding, tropomyosin is pulled away from the active sites on actin. Myosin can bind with actin forming a cross...

A) Resting membrane (prior to the initiation of an action potential) B) just before threshold to just after threshold (Depolarization) C) Rising phase of the action potential D) Falling phase of the action...
